疑问代词
1) 疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
指人: who, whom, whose
指物: what
既可指人又可指物: which
2) 疑问代词在句中应位于谓语动词之前,没有性和数的变化,除who之外也没有格的变化。what, which, whose还可作限定词。试比较:
疑问代词:Whose are these books on the desk? 桌上的书是谁的?
What was the directional flow of U. S. territorial expansion? 美国的领土扩张是朝哪个方向的?
限定词:Whose books are these on the desk? 桌上的书是谁的?
What events led to most of the east of the Mississippi River becoming part of the United States?
哪些事件使密西西比河以东的大部分土地归属于美国?
说明1:无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内。例如:
Which girls do you like best? 你喜欢哪几个姑娘?
What girls do you like best? 你喜欢什么样的姑娘?
说明2:Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
Who(m)did you meet on the street? 你在街上遇到了谁?(作动词宾语)
Who(m) are you taking the book to? 你要把这书带给谁?(作介词宾语,置句首)
To whom did you speak on the campus? 你在校园里和谁讲话了?(作介词宾语,置介词后,不能用who取代。)
说明3: 疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句末。例如:
For what do most people live and work? 大部分人生活和工作的目的是什么?(旧文体)
What are you looking for? 你在找什么?(现代英语)liuxuepaper.com
